Striking Distance and Interception Probability

IEEE Transactions on Power Delivery, 2008
The relation between the striking distance and interception probability is experimentally investigated under standard lightning impulse voltages of both polarities. By using the rod-plane gap as a reference case, results are presented relating to the discharge interception probability of an earthed rod inserted in the gap.

Low probability of intercept radar strategies

IEE Proceedings - Radar, Sonar and Navigation, 2004
To reduce probability of intercept, in most cases, the form and magnitude of the radar transmissions are designed to spread energy over as wide a range of dimensions as possible. Equally, in response to this, designs for electronic surveillance measures (ESM) systems have been postulated that increase receiver sensitivity.

Interception Probability and Shielding Against Lightning

IEEE Transactions on Power Delivery, 2009
A comprehensive analysis on shielding against lightning is presented. For an air terminal, the design of its protection zone and collection volume is introduced on the basis of simple working relationships which take into account, besides lightning parameters and air terminal height, the interception probability and use as a reference the striking ...

Computation of Intercept Probability Based on Functional Simulation of Front-End Interception

Applied Mechanics and Materials, 2013
Front-end intercept probability of reconnaissance equipment is a significant evaluation index of radar reconnaissance system. It shows the ability of discovering and detecting radar signal in the front of reconnaissance equipment. In order to obtain the relatively authentic intercept probability, first, rules of intercept judgment are elaborated.

Flight Vehicle Penetration Probability Evaluation against the Missile Intercepting

2021 International Conference on Intelligent Transportation, Big Data & Smart City (ICITBS), 2021
Traditional flight vehicle penetration effect evaluation is based on penetration miss distance. Because of the random distribution of miss distance, the traditional evaluation method brings much evaluation error and the evaluation result can only provide the successful penetration or not but can’t provide the penetration effect parameter caused by the ...

Low probability of intercept

IEEE Communications Magazine, 1983
LOW Probability of Intercept (LPI) analysis shows the effect of scenario-dependent parameters and detectability-threshold factors in jamming and nonjamming environments. The most significant improvement in LPI performance may be obtained by operating at Extremely High Frequency (EHF) and by maximizing the effective spread-spectrum processing gain and ...

The metrication of low probability of intercept waveforms

2010 International Waveform Diversity and Design Conference, 2010
In recent years, military radar operators have been concerned that the transmitted radar signals will beacon the presence of the radar to an enemy. If intercepted, the radar signals alert a target to an attack which could prompt evasive measures or countermeasures to be taken by the target including the possibility of a reprisal attack using an ...
